Wisconsin was originally home to Native peoples including the Ho-Chunk, Menominee, Ojibwe, Potawatomi, and Dakota Sioux. French explorers and fur traders arrived in the 1600s, followed later by British control and eventually American settlement after the Revolutionary War. The territory became part of the U.S. through the Northwest Ordinance and achieved statehood in 1848. Large numbers of German, Polish, and Scandinavian immigrants shaped the state’s culture, traditions, and politics. Wisconsin was a strong supporter of the Union during the Civil War and became known for progressive reforms in the early 20th century. Today, it retains a strong agricultural identity while also being recognized for manufacturing, higher education, and a vibrant cultural scene.
